Similarities

This isn’t too much and it may not have too big an impact in the long run. However, we cannot ignore the similarities between Doctor Strange and Iron Man. Both of them are geniuses in their domains – one as an arms developer, the other one as a surgeon. Both are handsome men, sporting just about the same amount of facial hair. Both find themselves at some turning point in their lives, meaning that they have to reassess everything they have previously done.
So if Tony Stark is captured and then refuses to build any more weapons, changing his entire personality in the process, Doctor Strange suffers the same kind of transformation. From a literal jerk, only set on making the most for himself, he becomes altruistic and finds a way to help even more people than before.
What does that mean?
Well, call us Cumberfans, but we do believe that Doctor Strange will be the biggest deal in the MCU starting with Phase IV, just like Robert Downey Jr.’s Iron Man was the face of the entire shared universe for three Phases.
